Two lights hovering over remote area of Catskill Mountains, made no sound, turned a sharp angle, and sped away

This encounter took place in the middle of the Catskill Mountains, at about 9pm in the dead of winter.
 I came home, and when I walked up onto the front porch, I noticed a light in the sky over the mountains. The sky was clear, and I live several miles from the next closest house, so it was perfectly quiet. 
I watched the light for a minute, but is was more of a glow more than anything else. Then, a second light came from ground level and slowly raised up in the sky to where the first one was. At that time, the two moved together (independently)toward my general direction. There was absolutley no sound, which I thought was peculiar.
Then the two craft slowly, unwavering, and perfectly straight, came over the trees, and at point, they must have been about 200-300 yards from where I was standing on the porch. They traveled for 30 seconds, and then the two accelerated, and did a turn that I can only describe as a sharp angle pinpoint turn, and sped away so fast that they left a light trail in the sky, before disappearing.
I was pretty frikkin' scared at that point, I broke the key off in the doorlock. Six years later, I was working as a carpenter on a new house, and I was talking about this incident while we were eating lunch. 
Another carpenter overheard me. He said he was at his home, a few miles down the road from mine, and saw the same thing in 1993!
Witness indicates that date is approximate.  PD
